非形态特征在粉虱分类中的运用（同翅目：粉虱科）

粉虱的分类主要利用第四龄幼虫 (蛹壳 )的特征而非成虫特征 ,而有的种类的形态有很大变异 ,完全依赖形态特征对某些种类 (特别是近缘种 )进行鉴定或鉴别是有困难的。因此 ,非形态特征的应用在粉虱分类中有一定的特殊价值。本文列举了一些可以用于昆虫分类的非形态特征 ,介绍了主要以非形态特征进行分类的特例——烟粉虱 Bemisia tabaci ( Gennadius)和银叶粉虱 Bemisia argentifolii Bellow &Perring的鉴别 ,并对非形态特征在分类中的合理运用进行了讨论。     

A NEW SPECIES OF THE GENUS CULICOIDES （JILINOCOIDES）（DIPTERA： CERATOPOGONIDAE） FROM THE GUANGXI ZHUANG AUTON. REG., CHINA
